They showed this rifle on that episode. It was inherited by the person that brought it. They didn't say what caliber as I recall. Fairly nice shape but with a significant rear stock crack. The owner brought a letter from BATF after he contacted them concerning the illegal barrel length. BATF made it "legal" for him to keep it according to the letter they displayed. I think they valued it at 6K. Interesting.
